CORNER-WALL CONSTRUCTION.

Application led December 7, 1925. Serial No. 73,699.

This invention relates to corner wall construction for furnaces and for other uses, particularly Where subject to material changes of temperature, and has for its object to produce a corner construction of simple, strong, durable and comparatively inexpensive construction, wherein the inner faces of the wall where expansion and contraction is negligible, is solid and comparativel rigid and the outer portion free to expan and contract. More specificially, the object is to provide corners of refractory tile of such form and arrangement that alternate courses of each wall rest wholly upon underlying courses of the same wall, and the other courses of each wall upon the underlying courses of both walls, and in which tiles of the same courses in both walls abut together transversely and longitudinally at the inner faces of the walls and are spaced apart outward of such abutting points to accommodate longitudinal expansion of either or both walls.

lVith the objects n amed in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which Figure 1 is a fragmental perspective view of a furnace embodying a corner wall construction in accordance with the invention.

Figure 2 is a. plan view of the same.

Figure 3 is a detail perspective .View of one of the tiles employed in the construction of the corner Wall.

In the said drawing, 1 indicates the inner walls and 2 the outer walls of a double wall furnace. .The walls are spaced apart as at 3, as customary. The invention is concerned only With the corners of the Vinner walls 1, the body portions of which are of refractory brick of conventional or other preferred type, except that at suitable intervals in each course, there will be tapered bricks B (one only appearing) to accommodate longitudinal expansion of the wall. This however, as it forms no part of the present invention is given no further consideration herein.

Forming the corners of the walls 1, are series of refractory tiles, alternate tiles of the series of each wall, overhanging the other tiles, the overhanging tiles of one wall lying in different courses from the corresponding tiles of the other wall. This arrangement is shown in Figures 1 and 2, and for conven# ience of identification, the tiles, although of identical form and size, are marked with the reference characters 4 for the overhanging tiles and 4 or the overhung tiles. This relation of the tiles accommodates the regulation or break-joint setting of the bricks, and also provides for 'a break-joint relation between the corners of connecting walls.

The tiles are flat, the same thickness as the brick, and of generally right-angle triangle contour, and so arranged that the hypotenuse faces of tiles of the same courses or levels of connectin walls, are spaced apart, alternate tiles of t e same walls being laid to project at their hypotenuse edges a half of the width of a brick beyond the corresponding edges of the interposed tiles, the projecting tiles of one wall being in different courses from the projecting tiles of the other wall so that the spaces between the corresponding courses of tiles of the two walls shall be in staggered relation and the projecting tiles of each wall rest upon and overlap the corresponding tiles of the other wall, and the alternate or non-projecting tiles of each wall shall rest jointl on the underlying tiles and brick work o its own wall. Each tile has a long. and two short parallel end edges, 5, 6 and 7, and a lon and two short parallel side edges 8, 9 an 10, and there is an edge 11 extending from edge 7 to edge 9, perpendicularly to a line bisecting the angle formed by the side edges 5 and 8, the said edge 11 paralleling an imaginary line, dotted at a, extending from the junction of edges 7 and 8, to edge 10 midway the length thereof, and through the intersection point of edges 6 and 9, the parts lying at the opposite side of line a from edges 5 and 8, constituting projections 12 and 13 for overlapping purposes, the former projecting the greater distance so that by abutting the edges 6 and 9 of a corresponding tile of the same course but of a dierent wall, such tiles shall be spaced apart along their edges 11. It will also be noted that by arranging superposed tile in staggered relation, as explained, the projecting parts 12 and 13 of one wall, overlap and rest upon corresponding parts of the tiles of the projecting courses of the other wall.

Under suicient heat in the furnace, the inner walls, will expand and contract longiwalls outward from the inner tudinally and thus respectively narrow and widen the spaces between the hypotenuse faces of the tile. The expansion and contraction of the walls at and near their inner faces, is negligible, hence the tiles in the saine courses of dilerent walls, to impart solidity and strength to the Walls, are set in abutting relation at their edges 6 and 9. The occasional bricks B are of course tapered outwardly as shown, to facilitate longitudinal expansion of the respective rtions thereof, thou h such tapered brie are not indispensa le.

. From the above description, it will be apparent that I have construction embodying the features of advantage set forth in the statement of the object of the invention, and it is to be understood that I reserve the right to make all changes falling within the spirit, and scope of the appended claims.

I claim: 1. A corner wall construction, comprising courses -of generally triangular tiles, the

hypotenuse sides of the tiles of the two walls forming the corner, being parallel and spaced slightly apart, alternate tiles of each Wall overhanging at their hypotenuse edges the corresponding edges of the other tiles of the same wall.

2. A corner wall construction, comprising courses of nerally triangular tiles, the hypotenuse sides of the tiles of the two walls forming the corner being parallel and spaced slightly apart, alternate tiles of each wall Voverhanging at their hypotenuse edges the produced a corner Wall correspondin edges of the other tiles of the same wa with the overhanging tiles of one wall overlapping and resting on the corresponding tiles of the other Wall.

3. A corner wall'construction, comprising courses of generally triangular tiles, the hypotenuse sides of the tiles of the two walls forming the corner being parallel and spaced slightly apart, alternate tiles of each wall over-hanging at their hypotenuse edges the corresponding edges of the other tiles of the same wall, the overhangng tiles ot each wall having projections at their hypotenuse edges, abutting corresponding projections of the overhung tiles of the other Wall.

4. A flat corner wall tile having intersecting outer edges and a broken or irregular hypotenuse edge extending in a line starting near an end of one of said outer edges and intersectin the other outer edge at the opposite end t ereof from the edge near which said line starts.

5. A flat corner wall tile having intersecting outer edges and a broken or irregular hypotenuse edge extending in aline starting near anend of one of said outer edges and intersecting the other outer 'edge at the opposite end thereof from the edge near which said line starts, the irregular edge forming a triangular inner projection and a Shallower outer projection extending at right angles to a line bisecting the angle formed by the intersecting outer edges.

In witness whereof I hereunto atiix my signature.
